Cancellations in ambulatory day surgery: Ten years observational study

Abstract Background Reasons for cancellation of booked procedures in ambulatory surgery need a detailed analysis in order to introduce corrective measures to lessen them. Methods Cancellations occurring the day before operation without patient replacement and procedures cancelled on the day of operation in 10 500 patients scheduled to be operated on in a multidisciplinary ambulatory surgery unit were analysed. Data were obtained from the incident register sheets and the database of the unit. Results A total of 424 patients were cancelled (4%). Reasons for cancellation were: acute medical conditions in 23.3% of cases, personal decision of the patient to refuse programming in 22.2%, non-attendance in 2.1%, failure to follow pre-operative guidance in 23.3% and unavailability of resources in 29%. These causes were preventable or possibly preventable in 57.1% of cases, difficult to prevent in 29% and not preventable in 13.9%. Conclusion More than half the cases of cancellation could be prevented. A rapid response of surgical departments to substitute patients, campaigns to increase the awareness of the population about the cost of health services and the implementation of pre-operative assessment guidelines must be considered.
